A. 3y : 2x

B. 2x : 3y

C. x : y

D. 2y : 3x

Answer: Option A

Solution(By Examveda Team)

2 men can do a work in x days
1 men can do a work in (2 × x) days
y women can do a work in 3 days
1 women can do a work in 3y days

	1 man	:	1 woman
Days	2x	:	3y
Efficiency	3y	:	2x

$$\eqalign{ & {\bf{Alternate:}} \cr & {\text{2M}} \times x = y{\text{W}} \times {\text{3}} \cr & \frac{{\text{M}}}{{\text{W}}} = \frac{{3y}}{{2x}} \cr & {\text{M}}:{\text{W}} = 3y:2x \cr} $$
